US accuses North Korea of Sony hack

The United States said Friday that North Korea was behind a cyber attack on Sony Pictures, warning that those responsible would face punishment, as an envoy for Pyongyang again denied involvement. Threats issued after the November attack prompted the movie giant to cancel the Christmas Day release of “The Interview,” a madcap satire about a CIA plot to kill North Korean leader Kim Jong-Un. In addition to the threats, Sony has seen the release of a trove of embarrassing emails, scripts and other internal communications, including information about salaries and employee health records.
